On the occasion of the three-hundredth anniversary celebrations of the birth of Jean-Jacques Rousseau (1712 – 1778), the Library of the City of Geneva has mounted an exhibition devoted to Rousseau's passion for music. The multimedia display features films, sound recordings and original scores by Rousseau, Rameau and other musicians of their time. In addition to live concerts and musical theatre, lectures and guided tours of the show are accessible via iPod, iPhone and Android.
